RAILWAY-TRACK CONSTRUCTION.

Application filed January 15, 1926. Serial No. 81,413.

Our invention relates to railway track construction, the improvements comprised therein being of particular value in the construction of street railway tracks in paved streets or highways.

It is .the primary objects of the present invention to provide durable and efiicient cushioning` means which permit of a limited yielding movement of the rails of a railway track in a vertical direction relative to a fixed and rigid supporting element, while maintaining the rails against horizontal displacement.

A further object of theinvention is to provide in addition to the above mentioned means, cushions which will separate the railsiof a track from the sur rounding rigid paving material in which the track is partially imbedded and permit the proper gauge and alignment to be maintainedindependently from the paving, and still another object is to provide a connection between the rails of the track and the ties to which they are attached, which is subject to elastic deflection or deformation in a yvertical direction to prevent the vibrations and shocks imparted to the rails by" moving loads from being transmitted to the ties or the foundation on which they are supported.

Bypthe use of our invention a railway track may be laid in a paved area and so constructed asV to have every advantage of.

theresiliency of a so-called open or unpaved track which is supported by wooden ties laid in the ground or upon ballast.

The cushioning and resilient connecting means employed in our invention as briey described hereinabove, lessen the noise and vibration Aincident tothe movement of the rolling stock along the railway, and absorb the shocks incident tothe operation of thel Considering furthermore that the cushioning and supporting means of our invention operate to yieldingly support the rails at the proper elevation, while ithey also maintain the proper gauge betweenthe rails and hold the rails in a vertical position or at any desired inclination thereto, it will be evident that the `invention is a decided advance in the art of street railway construction.`

In the accompanying drawings, we have illustrated different forms and arrangements of parts showing embodiments of our invention which adapt it for use under varying conditions, it being understood that all of said embodiments are within the scope and spirit of the invention ras set forth in the following description and dened in the hereunto appended claims.

Figure 17, a cross-section of the track, in which the resilient supporting means are formed as an integral part of the ties, and Figure 18, a fragmentary section in the plane 18-18, Figure 17.

Referring to the figures of the ldia-wings in their numerical order, the metal ties of the construction illustrated in Figures 1, 2, 3 and 6, are supported in a foundation 6 of concrete or other similar rigid material, and the rails 7 are laid in a plastic paving substance S, such as asphalt.

Cushions 9, composed of a plastic and elastic substance, such as asphalt or a mix-V ture of asphalt and other materials, or any other durable and flexible material, are interposed between the rails along the entire length thereof, and the ties and foundation upon which the rails are supported.

The cushions function in the operation of 'the' railway to absorb the shocks and vibrations produced by movement of the cars along the track and to prevent the same from being communicated to the foundation elements ofthe structure.

The rails of the track are furthermore Vsupported on the ties by means of resilient or vertical position or whatever inclination. lthereto which has been established.

flection of the rails 1s not communicated toV The desurrounding paving owing to the flexible nature of the paving in the case of its being 'asphalt or Vthat of the cushion interposed between the rails and the paving when the latter is constructed of rigid material.

rlhe form of the invention illustrated m Figures 4 and 5 di'ti'ers from the first described form only in that the position of the metal brackets is reversed so that they are fastened to the ties between the rails instead of at the outside of the same.

In the construction illustrated in Figures 7 and 8, the brackets or chairs 12 are of inverted U-shape and fastened to the ties at both ends and at opposite sides of the rails.

In Figures 9, 10 and 11 is illustrated a track laid entirely in a paving 13 of concrete, stone, brick or other rigid material.

In the use of concrete as shown in the drawings, the paving and the track foundation G may form a homogeneous mass. The rails are supported on elastic cushions 14 and resilient metal brackets 10 as before, but in order to provide for the yielding vertical movement of the rails, cushions 14 and 15 of elastic material are interposed between the railsl along the entire length thereof, and the rigid paving material in which the rails are laid.

The side cushions may be made integral parts of the cushions beneath vthe rails as best shown in Figure 11. lt will be appaient that the cushions and supporting means will completely support the loads imposed on the rails and will prevent of stress and shocks incident to the movement of the load being transmitted either to the ties, the track foundation or the surrounding road- `way material. i l

In the form illustrated in Figures 14 and 15, the resilient brackets 16 which support the rails upon the ties, are provided With upwardly extending arms,` so that they may be fastened to the webs of the rails, and the cushions 17, 18 and 19 beneath and at the sides of the rails are made of wood.

In this construction or other similar constructions, the rails may be supported between the ties upon wooden blocks 20 as illustrated in Figures 12 and 13, in which case clips 21 are spiked on the blocks to hold them in place by engagement with the feet .of the rails.

yIn order to increase the resiliency of the support, cushions 22 of plastic material like those employed in the other forms of the invention l'iereinbcfore described may be interposed between the feet of the rails and the wooden blocks as illustrated at Fig-V ure 13.

In Figure 16 has been shown a resilient bracket 23 of Z-shaped form, fastened to the tie beneath the rail, and in Figures 17 and 18 the brackets 24 are made integrally with the ties 25 by cutting and bending upwardly parts of the metal of which they are eomposed. Y

The ties are made of channel bars as shown m Figure 18, and they brackets are cut out of the upper flanges thereof and bent upwardly lo engage the feet of the rails to which they are fastened as before.

Having thus described our invention, what we claim and desire to secure by Letters Patent. is:

1. In railway track construction, the coinbination with the rails and ties of a railway track, a. foundation element, and a paving in which the rails are laid, of means of resilient material fastening the rails to the ties, resilient cushions supporting the rails on the foundation element, and resilient cushions between the sides of the ties and the paving.
